The bowen's discontinuous reaction series involves continuously with falling temperatures. o true o false mafic minerals, where the reactions occur at specific temperatures. continuous reaction series involves the mineral plagioclase, where the reactions occur question 4 in the chemical evolution of magma, there are internal and external processes. internal processes include: magma fixing and assimilation. while external processes include: fractionation, and crystal settling. o true false 10 question 5 what does the viscosity of magma depend on? temperature, chemical composition, and volatile content. temperature the rate at which the magma formed the place at which the magma formed.

Question 3: True

Question 4: False

Question 5: option a

Explanation:

Question 3:

In the Bowen's Reaction arrangement, the persistent arrangement portrays and clarifies the development of the plagioclase feldspars as they advance from being calcium-rich to incfeasingly sodium-rich with consistently falling temperature conditions.  

Then again, the discontinuous arrangement depicts the development of the mafic minerals, for example: pyroxene, olivine, biotite mica and amphibole each at an unmistakable temperature.

Question 4: False

Fractionation and crystal settling are a piece of partial crystallization and they are internal procedures.

Question 5: option a

Viscosity of a given magma increments with expanding silica content, diminishing temperature and diminishing volatile substance.
